An aeroplane takes off from (1,2,0) and climbs in the direction (-11,10,2)
part a) how close does the areo plane get to the top of an aerial mast at (0,2,1)
AB=b-a = (0,2,1)-(1,2,0) = (-1,0,1)
D(hat)= (-11,10,2)/15
AB.D(hat) = (11/15 + 2/15 = 13/15
root(AB - AB.D(hat)^2 )= root(2 - (13/15)^2)
=root(281)/15=1.1175
this is correct
-----
This is the part I'm having trouble with
PARTB)
Find the location of the areoplane after it has traveled 60km
60^2 = AB-AB.D(hat)
A = (1,2,0) B =(x,y,z)
what to do now?
